Lichen planus is an inflammatory disease characterized by reddish-purple, flat-topped bumps that may be very itchy. They can be anywhere on the body, but seem to favor the inside of the wrists and ankles. The disease can also occur on the lower back, neck, legs, mouth, genitals, and in rare cases, the scalp and nails. Thick patches may occur, especially on the shins. Blisters are rare.. While the typical appearance of lichen planus makes the disease somewhat easy to identify, a skin biopsy may be needed to confirm the diagnosis. The cause of lichen planus is not known.
What is the treatment for Lichen Planus?
There is no known cure for lichen planus but treatment is often effective in relieving itching and in improving the appearance of the rash until it goes away. Since every case of lichen planus is different, no one treatment is perfect. The two most common treatments include the use of topical corticosteroid creams and antihistamine drugs taken by mouth. Both work to help itching. More severe cases of lichen planus may require stronger medications such as cortisone taken internally, immunosupressants or ultraviolet light treatments.
